Apple iTunes compare

iTunes 11 is a much-needed refresh with a new interface and a useful MiniPlayer, but it's still a little overly complex for its own good.

Office Mobile is worth downloading if you're a current Office 365 subscriber, but with only basic editing features, this app should be free for all.

With its enormous catalog of on-demand streaming music and its built-in social features for discovering new tunes, Spotify is an absolute must-have for audiophiles and casual listeners alike. But free users, beware of intermittent eardrum-piercing ads.

Amazon Instant Video is only instant if you're a Prime subscriber or once you've already purchased content from Amazon's Web site, but the lower cost for some videos might make it worth your while.
